an analysis of historical divides and historical influences on current social work practice with respect to policy advocacy and action

Post an analysis of historical divides (such as the schism between Jane Addams and Mary Richmond) and historical influences on current social work practice with respect to policy advocacy and action. Do such schisms exist in contemporary social work? If you think these divides exist, how do they prevent social workers from fulfilling their ethical obligation(s)? Are they important differentiations?
